Awesome plan. Here’s a ready-to-run Blender script that builds a quick 3D from your floor plan, puts each room as a separate object/collection, and lets you toggle the plan image as an underlay for alignment. It uses feet/inches from your drawing and creates clean extruded room “volumes” you can later detail. > How to use 1. Open Blender → Scripting tab → new text → paste → Run. 2. (Optional) change FLOORPLAN_IMAGE_PATH to your PNG/JPG. 3. Tweak sizes/positions in the rooms dictionary if you want micro-adjustments. 4. After it runs: Collections panel has one collection per room; walls/floors are separate objects so you can assign materials or hide rooms easily. --- # BLENDER 3.x SCRIPT — build quick 3D from a 2D plan and separate rooms # Paste into Blender's Text Editor and click "Run Script". import bpy import math # ========== USER SETTINGS ========== FLOORPLAN_IMAGE_PATH = "" # e.g. r"C:\Users\you\Downloads\plan.png" (leave "" to skip) WALL_THICKNESS_FT = 0.5 # ~6 inches walls WALL_HEIGHT_FT = 10.0 # typical wall height FLOOR_THICKNESS_FT= 0.5 ELEVATION_FT = 0.0 # Z offset for ground floor ORIGIN_AT_LOWER_LEFT = True # keep (0,0) at lower-left of site for easier thinking # Overall site size from your drawing (outer rectangle) SITE_WIDTH_FT = 33 + 3/12 # 33'3" SITE_DEPTH_FT = 52.0 # Quick helper to convert ft→m (Blender default meters) FT_TO_M = 0.3048 def ft(v): return v * FT_TO_M # ========== CLEAN SCENE & UNITS ========== def reset_scene(): bpy.ops.object.select_all(action='SELECT') bpy.ops.object.delete(use_global=False) for c in bpy.data.collections: if c.users == 0 and c.name not in {"Collection"}: bpy.data.collections.remove(c) # units in feet for UI convenience scene = bpy.context.scene scene.unit_settings.system = 'IMPERIAL' scene.unit_settings.scale_length = FT_TO_M reset_scene() # ========== REFERENCE IMAGE UNDERLAY ========== def add_plan_image(path): if not path: return None # add as Empty image so scale is easy img = bpy.data.images.load(path) empty = bpy.data.objects.new("Floorplan_Ref", None) empty.empty_display_type = 'IMAGE' empty.data = img # scale empty to site size (X right, Y up) empty.empty_image_offset[0] = 0.0 empty.empty_image_offset[1] = 0.0 empty.scale = (ft(SITE_WIDTH_FT), ft(SITE_DEPTH_FT), 1.0) # place origin at lower-left if ORIGIN_AT_LOWER_LEFT: empty.location = (0.0, 0.0, ft(ELEVATION_FT)+ft( WALL_THICKNESS_FT*0.5)) else: empty.location = (-ft(SITE_WIDTH_FT)/2, -ft(SITE_DEPTH_FT)/2, ft(ELEVATION_FT)) # put it in its own collection col = bpy.data.collections.new("00_Reference") bpy.context.scene.collection.children.link(col) col.objects.link(empty) # make it low opacity & unselectable empty.empty_image_opacity = 0.4 empty.hide_select = True return empty add_plan_image(FLOORPLAN_IMAGE_PATH) # ========== GEO HELPERS ========== def add_box(name, w_ft, d_ft, h_ft, x_ft, y_ft, z_ft, collection): bpy.ops.mesh.primitive_cube_add(size=1.0, location=(ft(x_ft), ft(y_ft), ft(z_ft))) obj = bpy.context.object obj.name = name obj.scale = (ft(w_ft/2), ft(d_ft/2), ft(h_ft/2)) collection.objects.link(obj) # unlink from default collection if linked twice try: bpy.context.scene.collection.objects.unlink(obj) except: pass return obj def ensure_collection(label): if label in bpy.data.collections: return bpy.data.collections[label] c = bpy.data.collections.new(label) bpy.context.scene.collection.children.link(c) return c # ========== PLAN LAYOUT (APPROX FROM YOUR DRAWING) ========== # Coordinates: (0,0) at lower-left (balcony/portico side), X to the right, Y upward (toward top of plan) # Provide center positions and sizes for each room.

Each room is in its own collection. Tweak sizes/positions as needed.") Notes The script places rooms using reasonable approximations from your plan (all the given dimensions are honored; relative placement matches the drawing’s intent). Nudge the centerX_ft/centerY_ft values to align exactly with your plan if you like. Every room has: a floor slab + hollow wall shell. That keeps materials and visibility simple. To export for other tools/apps: File → Export → glTF 2.0 (recommended) or OBJ/FBX. If you want a version that tries to auto-trace the plan image with OpenCV and spit out a Blender-ready SVG, I can drop that too—but this Blender-only version is the quickest way to get a clean, editable 3D with rooms already separated.
